可收缩和可伸缩的经口输送钉砧装置 Telescopically retractable and oral delivery anvil means

技术领域 FIELD

[0001] 本发明涉及一种外科吻合器具,尤其是涉及一种可收缩和可伸缩的经口输送钉砧 [0001] The present invention relates to a surgical stapling instrument, particularly to a collapsible and retractable anvil for oral delivery

目.0 Head .0

背景技术 Background technique

[0002]当前,针对食管癌、贲门癌等消化道肿瘤的微创外科治疗常应用经口输送钉砧装置,该经口输送钉砧装置包括经口钉砧置入装置和环形吻合器。 [0002] Currently, the treatment of minimally invasive surgery for esophageal cancer, cardiac and other gastrointestinal tumors often used for oral delivery of the anvil means, the anvil means oral delivery include oral and anvil means into an annular stapler. 当前的经口输送钉砧装置虽然使消化道重建微创外科吻合成为可能,但是在临床应用过程中仍有以下不便之处: The current oral delivery device although the anvil digestive tract reconstruction minimally invasive surgical stapling possible, but in the course of clinical applications are still less inconvenience:

[0003] I)目前钉砧的直径与吻合器直径一致(大于或等于2.5cm),术中口腔一般都有气管插管阻挡,因而术中经口置入直径大于或等于2.5cm的钉砧进入食管操作相对困难; [0003] I) consistent with the diameter of the current stapling anvil diameter (greater than or equal to 2.5cm), oral surgery generally intubation barrier, thus intraoperative orally anvil into 2.5cm diameter greater than or equal to into the esophagus operation is relatively difficult;

[0004] 2)术中经口置入直径大于或等于2.5cm的钉砧进入食管,自食管入口到达吻合部位时,容易导致食管粘膜损伤。 [0004] 2) intraoperative orally into 2.5cm diameter greater than or equal to the anvil into the esophagus, the esophagus when the inlet from reaching the anastomotic site, easily lead to damage esophageal mucosa.

[0005] 3)因钉砧长度需要与环形吻合器匹配,钉砧的长度大约5cm,因钉砧为金属硬质材料,术中置入的过程相对困难,特别是经过咽喉弯曲部进入食管过程尤为困难; [0005] 3) The need to match the length of the anvil and an annular stapler, the anvil of a length of about 5cm, because the anvil is a metal hard material, intraoperative placement procedure is relatively difficult, especially through the throat into the esophagus during the bending portion particularly difficult;

[0006] 4)术中经口置入长度大于或等于5cm的钉砧进入食管,自食管入口到达吻合部位时,容易导致咽喉部损伤。 [0006] 4) inserted orally intraoperative length greater than or equal to 5cm anvil into the esophagus, the esophagus when the inlet from reaching the anastomotic site, easily lead to damage to the throat portion.

[0007] 中国专利CN1252255公开一种外科用管型吻合器,实现钉砧位置调节机构具有快慢调节功能,指示机构既能指示钉砧相对钉筒移动的所有的重要位置又能指示吻合钉成形后吻合钉的夹紧程度,保险机构仅在待吻合组织达到适合吻合操作的夹紧厚度的范围时才允许击发手柄被击发,特别适宜用于吻合位于人体深部的消化道器官或在内窥镜下吻合人体的消化道器官,还特别适宜在流水线上大规模地生产低成本的一次性使用的外科用管型吻合器。 [0007] Chinese Patent CN1252255 discloses a tube-type surgical stapler, the anvil to achieve the position adjusting mechanism having a speed adjustment function, indicating means indicate both the anvil relative to the staple cartridge moves all the important positions can indicate staple forming clamping staples degree range, insurance only be stapled to achieve suitable thickness of the clamping tissue stapling operation is allowed only when the firing handle fired, stapling particularly suitable for deep organs of the body portion is located in the digestive tract or endoscopically consistent with the body's digestive tract organs, but also particularly suitable for tube-type surgical stapler low-cost production on a large scale in the pipeline disposable.

[0008] 中国专利CN2461494公开一种外科用管型吻合器,在吻合操作执行前和执行时,钉砧与钉砧拉杆的定位杆之间刚性联接;在吻合操作完成后,钉砧才可侧倾转动,便于侧倾转动后的钉砧从较小口径的吻合口退出,以避免撕裂吻合口。 [0008] Chinese Patent CN2461494 discloses a tube-type surgical stapler, and before the stapling operation is performed, when executed, the rigid coupling between the positioning rod and the anvil of the anvil rod; after the stapling operation is completed before the anvil side camber rotation, to facilitate rotation of the anvil roll from the stoma exit smaller diameter, in order to avoid tearing the anastomosis. 其中大部分零部件由结构和形状简单的冲压件、注塑件和圆管制成。 Most parts of simple structure and shape of stamping, injection molding and tube are made. 特别适宜用于吻合位于人体深部的消化道器官或在内窥镜下吻合消化道器官,还特别适宜在流水线上大规模地生产低成本的一次性使用的直颈式或弯颈式外科用管型吻合器。 Particularly suitable for stapling gastrointestinal organs of the body located in the deep portion of the alimentary tract anastomosis or endoscopically, is also particularly suitable for the production of linear low-cost mass-neck in the pipeline disposable surgical or curved neck tube stapler.

发明内容 SUMMARY

[0009] 本发明的目的在于针对当前的经口输送钉砧装置存在的上述缺点,提供一种改进的可收缩和可伸缩的经口输送钉砧装置。 [0009] The object of the present invention is the above-described disadvantages of the conveying means for the current anvil orally, to provide an improved collapsible and retractable anvil oral delivery device.
